The eval workflow for startup AI teams

Ship AI changeswith confidence.

Test prompt and model changes on real datasets before release. Compare quality, latency, and cost in one place, and catch regressions before they reach users.

Benchmark-backed ROI

Cut model costs without compromising what ships.

On a benchmarked production task, we reached 98% accuracy parity with GPT-5.4 while reducing token costs by 80%.

EvalForge helps startup AI teams identify the lowest-cost model that still clears their quality bar, before a release reaches users.

Benchmark-backed resultLocal + hosted modelsHugging Face importsHuman review workflowCost and latency visibility

AI teams are still shipping prompt and model changes with too much guesswork.

Manual checks miss edge cases. Regressions slip into production. Costs rise without visibility. And every model change becomes a bet instead of a measured decision.

Manual spot checks

A few examples in a playground do not tell you what will happen in production.

Silent regressions

Without benchmarks and traceable experiments, quality drops are easy to miss.

Blind tradeoffs

Teams often discover cost and latency problems only after a change is already live.

A simple workflow before every release

EvalForge gives your team a repeatable process for deciding what is safe to ship.

1. Build datasets
2. Configure models
3. Run experiments
4. Score outputs

Agent evaluation is next.

EvalForge is expanding beyond prompts and single-model runs. We’re designing support for evaluating multi-step agent workflows with the same benchmark discipline, observability, and cost visibility.

Think traces, intermediate decisions, tool usage, failure points, and final outcomes measured in one place before agent behavior reaches production.

Trace-level visibility

Inspect each step an agent takes, not just the final output.

Tool-call review

Evaluate how reliably agents use tools and external systems.

Step-by-step scoring

Measure failure points, recovery behavior, and final task success.

Release confidence

Ship agent workflows with the same rigor as prompt changes.
